I was printing some ABS on my modified Anycubic I3 Mega overnight, when I awoke to this horror of a destroyed glass print bed…

Now the question remains, how to actually fix this? One part is still firmly attached to the Bed and I fear this may destroy the Bed even more.

And I obviously need a new Print bed, but I can’t find the exact replacement, so should I even get a replacement Ultrabase? I saw that there are magnetic PEI beds available, but I am unsure if it is worth the 80-100€ for this.

Edit: Since the glass is glued to the 1.5mm aluminium heater PCB (and I already had to resolder the broken off wires once) I was looking at complete replacements at first, which why the price is relatively high

    I know nothing about 3d printing. What would happen if you took sandpaper to both sides after cleaning it up and put JB weld on it? If the surface is scratched for the weld to hold I don’t see why it wouldn’t work?

    Maybe someone else can tell us why it’s a bad idea.

      It might work, but you generally want to have a flat surface and it needs to stand up to extended periods of temps up to 110°C and I’m pretty sure this is borosilicate glass

      But I also can’t get the glass shards off the printed parts, so this is pretty much a moot point

        “J-B Weld can withstand high temperatures up to 500 °F (260 °C) continuously and up to 600 °F (316 °C) for short periods. It is designed for bonding various materials and is resistant to shock, vibration, and temperature fluctuations.”

        I’ve used it to put a chunk of engine block back on a motorcycle that got ripped off by a drive chain coming off and catching a bolt. Held it from leaks and drove it for a few years after that. I’m not familiar with the glass you use and such, probably best to research first.

        Sorry if it couldn’t help due to the shards you’re talking about. Best of luck mate. It works like mixing two putties together and their chemical reaction does the weld at normal temperatures so you don’t need electric/gas machines, just patience to not get it all over you hands, rags w.e
